IMPROVEMENT IN SASH-FASTENERS.

Specification forming part of Letters Patent No. 206,664, dated August6, 1878; application filed May 17, 1878.

To all whom it may concern:

Be it known that we, WILLIAM H. CoFF- MAN and NATHANIEL HAvENs, ofCarroll, in the county of Fairfield and State of Ohio, have invented anew and useful Improvement in Sash-Fasteners, which improvement is fullyset forth in the following specification and accompanying drawing, inwhich- Figure 1 is a view of the inside face of the window-frame; Fig.2, perspective enlarged view of the fastening device; Fig. 3, sectionalview of Fig. 2 through the line :10,- Fig. 4, portion of window-sash,showing ratchet-bar on the side of the same. Fig. 5 is a plan view,showing arrangement of the springs.

The object of our invention is to provide a convenient and simplesash-fastener, so constructed that it can be adapted for fastening bothupper and lower sash, and arranged in such a manner that when adjustedon the frame for one sash both sashes can be operated thereby, thussaving the cost of a fastener for each sash. It has also the additionaladvantage that the fastener can be manufactured of any kind of metal,and is not liable to getout of order.

It consists of a lock-piece or case, E, which is mortised, preferably,in the left windowframe, so that the face thereof will be even with thesurface of the frame A. The said case or lock is placed midway betweenthe bottom and top of the frame at a point where the upper part of onesash and the lower part of the other sash meet. The case B has two steelspring-plates, G C, fastened at one end to the inner side of itsface-piece, as shown at H, the opposite'ends thereof being provided eachwith a cog or catch, D D, cog D being fastened to the end of spring 0,and cog D to the end of the short spring 0, below spring 0. The cogs D Dpass through apertures or slots I) b in case B, and pass beyond thesurface of said case a slight distance.

At a suitable distance from the rigid point H a knob, E, passes throughthe case B, and is attached to spring 0, and knob E is attached to theshort spring 0 in a similar way.

Fig. 4 represents a portion of the sash A, showing the attachment of theratehetbar G to one of its edges. The teeth in this bar are made tocorrespond with the cog D. In like manner the ratchets in the lower sashcorrespond with the cog D.

In adjusting and operating this device, we first place the lock in theframe, as shown in Fig. 1. The stops a a. a are then placed in theframe. The lock or case will be so constructed that the cog I) willoperate in the groove which receives the upper sash, A, and the cog D inthe groove in which the lower sash, A, slides. The ratchetbar G is madeas long as the sash.

e will now suppose that both sashes are closed, as in Fig. 1. If it isdesired to raise the lower sash, press on the knob E. The free end ofthe spring will be depressed, and the cog D released from ratchet-bar G.In the same way, by depressing the knob E, the cog D will becomedisengaged from the ratchet, and the sash can be lowered.

It will be seen that there is no pressure or weight of the sash on thespring, which is the great ditfieulty with many of the othersashfasteners.

The lock can be fastened to the frame rigidly by means of screws throughthe holes F F.

Having thus described our invention, what we claim as new, and desire tosecure by Let'- ters Patent, is-

The combination of the plate B, recessed into the side of thewindow-casing, the two springs U 0, attached to the said plate andprovided with stop-lugs D I), and push-pins E E, with the sash-rack G,all arranged as described, for holding both sashes in any desiredposition, substantially as described.

In testimony we have hereunto set our hands this 4th day of May, 187 S,in the presence of witnesses.
